PATENT frieren 'ROLL FOR JORDAN ENGINES.

SPECIFICATION forming part of Letters Patent No. 533,857, dated February12, 1895. Application filed April 9, 1894. Serial No. 506,820. (Nomodel.)

T all whom it may cocern.- l

Be it known that I, EDWIN W. BARTON, a

, citizen of the United States, and a resident of v Lawrence, in thecounty-of Essex and State of Massachusetts, haveinvented new and usefulImprovements in Rolls for Jordan En,- gines, of which the following,taken in con- Dection with the accompanying drawings, is aspecification.

This invention relates to improvements in rolls for Jordan engines andit is carried out ever they occur on the different parts of thedrawings.

A represents the conical -Jordan roll secured to the-shaft B as shown inFig.'1. The exteriorV of the roll A has a series of annular bearingsurfaces A', A', preferably turned and trued on which are shrunk orotherwise iirmly secured the metal blade holding rings C, C, which arepreferably placed against abutting annular shoulders or projections a,

' a, on the exterior of the "roll A as shown in Fig. 1. r

D, D, represent the detachable blades or knives having a series ofpreferably elongated or slotted perforations d, d, by means of whichsaid blades may be lockedonto the blade-holding rings C, C, as willhereinafter be described. lIn addition to such perforations I prefer tomake on the under side of each blade or knife a series of notches or cutaway portions d', d', as shown in detail in Figs. l and 6, although suchnotches may be dispensed with if so desired without departing from theessence of my invention.

Each ring C is provided with a series of notches C C', adapted toreceive the blades D, and in practice I prefer to construct each of suchnotches so as to be capable of receiving and holding two knives orblades as will hereinafter be more fully described. One end of eachnotch is open and there provided with'inwardly projecting locking lipsC, Q` adapted to be hooked into the blade perforations d, d, when theblades-D, D, are to be vattached to the blade holding rings of thelroll. The opposite end of each notch C is -provided with one or twosteady grooves C8,

C3, (Figs. l and 4) adapted to receive and steady the blade or blades Dwhenlocked in position on the blade-holding rings of the roll. Inattaching a blade D to the roll I hold it above the said roll as shownin the upper portion of Fig. l and drop it into the notches C', C', onthe rings C, then move it slightly sidewise so as t o cause theprojection C to enter the perforation d, after which the blade is movedtowardthe larger end of the roll so as to cause the edge of the bladeadjacent to the cut away portion d to enter the groove C3 as fully shownin Fig. 6.. W henthe blade is thus hooked into position a space Eis leftbetweenI its inner edge and the outer circumference of the roll. Theother blades are then hooked onto the rings C, C, in a like manner afterwhich `the wood lling bars F, F, are driven'between the successiveblades, such filling pieces having out away parts f, f, (Fig. l) adaptedto receive the rings C, C, when l driven in between the blades.

The inner edge of each Wood filler F is driven far enough to.restagainst the periphery of the roll, that is below the inner edge ofthe blades Where it is free to expand laterally intoV the space E abovementioned thus forming a lock whereby said wood fillers are firmly heldin position and prevented from working loose as fully illustrated inFig. 5.

Having thus fullydescribed the nature, construction, and operation of myinvention, I wish to secure by Letters Patent and claiml. A taperingJordan roll having a series of blade holding rings combined with aseries of blades secured thereto and intermediate wood llers havingtheir innerv edges extended below said blades and adapted to enter aspace between the blades and roll,

substantially as and for the purpose set forth.

2. A tapering Jordan roll and blade holding rings secured thereto, andhaving notches and lateral locking projections combined with bladeshaving perforations adapted to receive such lock projections and cutaway recesses IOC) on the inner edge of said blades and-interf mediateWood fillers, substantially as and for the purpose set forth.

3. A tapering Jordan rolland blade holding rings secured thereto andhaving notches and lateral locking projections and steady groovescombined with blades having perforations adapted to receive such lockingprojections and cut away recesses on the inner edge of said blade andintermediate Wood lllers, substantially as and for the purpose setforth.

4. A tapering Jordan roll having blades secured on its periphery but notin contact therewith combined with intermediate Wood fillers extendingbelow the inner edges of said blades so as to allow the inner portion I5of such wood filler to expand laterally in the space between the rolland blades, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specication, in thepresence of 2o tWo subscribing witnesses, ou this 6th day of April, A.D. 1894.

EDWIN W. BARTON.
